ARTHUR B. HAYENER, OF WALTHAM, MASSACHUSETTS, ASSIGNOR TO JUDSON L. THOMSON, MFG. 00., A CORPORATION OF MASSACHUSETTS.

HOPPER FOR FEEDING RIVET-GAPS.

To all whom it may concern I Be it known that I, ARTHUR R. HAVENER,

a citizen of the United States, residing at Waltham, in the county of Middlesex and 5 State of Massachusetts, have invented new and useful Improvements in-Hoppers for FeedingRivet-Caps, of which the following is a specification.

This invention relates to a hopper for 10 separating articles having .a recess in one face thereof. from a mass of the same and feeding them one by-one to a raceway or chute. 1

The hopper is particularly adapted for separating and feeding rivet caps which have a'recess in one face thereof and an inwardly projecting annular flange surrounds ing said recess, and furthermore said hopper is particularly adapted for separating and feeding rivet caps which have a recess in one face thereof, a projection within said recess and an inwardly projecting annular flange surrounding said recess.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings: Figure 1 is a plan view of my improved hopper with the cover removed. Fig. 2 is a sectional elevation taken on line 22 of Fig. 1, with the cover in position. Fig. 3 is a sectional elevation taken on line 33 of Fig. 1. Fig. 4 is a detail sectional elevation taken on line 44 of Fig. 2; Fig. 5 is a detail plan of the remover plate. Fig. 6 is an enlarged sectional elevation taken on line 2-2 of Fig. 1, illustrating one of the rivet caps suspended upon one of the pins.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 10 is the casing of the hopper and 11 the cover. The casing 10 has a bracket 12 thereon by means of which it is fastened to the frame 13 of the machine in connection with which the hopper is to be used. A picker plate 14 is rotatably mounted in the casing 10 and is rotated by means of a shaft 15 fastened thereto by a pin 16 and journaled to rotate in a bearing 17 in the casing 10. A rotary motion is imparted to the picker plate by suitable mechanism connected to the shaft 15 by a universal joint 18 which is rotated by means of a shaft 19 journaled to rotate in a bearing 20 in the Specification of Letters Patent.

frame 13. -The upper face'2l of the picker plate 14 is inclined andan annular flan e 22 is provided on the upper face of said picker :plate adjacent to the periphery thereof, the upper face 23' of said flange being inclined toward the'upper face 21 of said picker Pl e A series of projections 24, preferably in the form of pins, are provided uponthe picker plate 14. Each of said projections is so formed as to be adapted to project into a recess 25 in the rivet cap 26 between the edge of the flange 27 and the center of said cap. Said projections are also so constructed and arranged as to project into that annular portion of said recess which is located at a greater distance from the center of said cap than is the inner edge of said flange. The projections or pins 24 are preferably of less diameter where they project into said recess than one-half of the width of said recess and said projections extend. beyond the face 21 of the picker plate 14 to'such an extent that the rivet cap will be tipped at an angle to the inclined face 21 of the picker plate when said rivet cap is engaged by one of said pins, as illustrated in Fig. 2.

The rivet caps 26 are each provided with a projection 28 in the center thereof which is located in the recess 25 and projects from the base of the rivet cap into said recess and also with a flange 27. The flange 27 is an annular flange and projects inwardly toward the center of said recess extending partly thereover, as distinctly shown in Fig. 6.

The pins 24 each have preferably an annular flange'29 thereon constituting a head, which is so constructed and arranged as to project between the rivet cap flange 27 and the base of said rivet cap and into that annular portion of said recess which is located at a greater distance from the center of said cap than is the inner edge of said flange. Said flange 29 constitutes a lateral projection, therefore, and is located on the outer end of the pin or projection 24, while adjacent to said flange is.an annular groove 30 formed in the peripheryof said pin 24.

The rivet caps pass out of the hopper onto a raceway 33 which projects into the interior of said hopper and is inclined at an angle to the inclined face 21 of the picker plate. The portion of the raceway which projects into the hopper confollows: The rivet caps in mass are project beneath sides of the pin 24 and as the rotation of the forms the function of removing the rivet caps from the pins in the picker plate. The cover 34 is slotted at 36 and its inner end lies in advance of the inner end of the remover late 35. Said base has a slot 37 at one si thereof through which the rivet ca s can pass back into the hop' or when said raceway is filled up to sai slot 37 with rivet caps. The upper endof the remover plate 35 is also slotted 'at38 to allow the pins 24 to a'ssalong beneath said remover plate an while said are so passing beneath said remover p ate the ears 39 the rivet cap on opposite picker plate 14 continues-the pin 24 pushes the rivet cap alon the upper. face of said remover plate unti by the combined action of said in and remover plate, saidcap is lifted o of said pin wh1 through the slot 38. The rivet capwhich has been removed from said'pin then slides down the base 35 beneath the cover 34 and onto the raceway 33..

The general operation of the device is as placed in the casing of the hopper until said casing is partly filled, the rivet caps being located in mass at the lower end of said hopper. The picker plate is rotated by any suitable means through-the medium of I the shaft 19, universal joint 18 and shaft and as the picker plate passes around through the lower end of the casing the pins 24 pick up the rivet caps, ing into the recess 25 1n the rivet cap between the edge 27 and the projection 28, while the flanges or heads 29 of said pins 24 constituting the upper ends of said projections project into said recess between the annular flange 27 and the base of said rivet cap and into that annular portion of said recess which is located at a greater distance from the center of said cap than is the inner edge of said flange, thus securely holding the rivet cap on the pin and preventing its accidental dislodgment therefrom. Said rivet caps are then carried around as illustrated in Figs. 1, 2 and 6, hanging by their flanges on the heads of the pins 24, with their lower edges resting against the inclined face 21 of the picker plate 14, and with the edges of the flanges 27 of said rivet caps projecting into the annular grooves 30 in said pins 24. All of the rivet caps which are engaged by the pins 24 in the manner illustrated in Fig. 2- that is, recess 25 and beneath the flange 27, will be carried by said pins around to the slotted opening 36 in the cover 34, and as said pins feed the rivet cap still farther in the direction of the arrow a (Fig. 1) the pins will pass downwardly through the slot 38 in the remover plate 35, while the ears 39 will lift the rivet cap base and along the raceway 33.

'which do not become lod e the pin passes each pin pro ectcombination, a casing,

with their heads projecting into the from the end of the pin 24 and said rivet cap will then slide down the deflector plate 40 is pro 'dedto deflect ged upon the ms toward the, lower end of the picker p ate, such caps being subsequently picked up. by

Asuitable the pins on the icker. plate and carried up, 7 and around in c direction ofthe arrow a to the raceway as hereinbefore-described.

Having thus described my invention, what feedingrivet caps prohaving an inwardly projecting annular flange surrounding said recess having, in combination, a. casing, a picker plate rotatably mounted in said casing and having an inclined upper face and a projection on said upper face arranged to project into said recess, said projection having an annular flange thereon constructed and arranged to project laterally therefrom and between said rivet cap flange and the base of said rivet cap.
